RESILIENT TIRE Specification of Letters Patent.

Patented June 1, 1909.

Application filed October 28, 1907. Serial No. 399,610.

To all whom it may concern:

citizen of the United States, residing at Los Angeles, California, haveinvented a new and useful Resilient Tire, of which the following is aspecification.

An object of this invention is to provide a tire for use on automobilesand other vehicles that will be practically as resilient as tires now inuse and can be manufactured at less cost and out of more durablematerial than the rubber tires now commonly used to secure a yieldingresilient support for the vehicle.

In order to produce my improved tire, I employ a tubular frame composedof a multiplicity of metalic plates, said plates being provided withinterlocking extensions preferably in the form of curled lips forholding said plates together to form the side and tread portions of thetire. Resilient braces may be employed within the tire and incombination with the aforementioned plates to give the necessarystrength to the tire.

Referring to the accompanying drawings which illustrate the invention:Figure 1 is a cross section of the tire shown attached to an automobileor bicycle wheel provided with well-known rim construction. Fig. 2 is aside elevation partly broken away and partly in section of a segment ofthe wheel and tire shown in Fig. 1. Fig. 3 is a view showing a somewhatmodified form of the tire. In this view the tire and the wheel to whichthe same is attached are adapted to carry heavier loads than the tireand wheel shown in Fig. 1. Fig. 4 is a longitudinal section of a segmentof the tire on line XX of Fig. 3. Fig. 5 is a cross section of the rimof a bicycle wheel showing the tire as adapted to be applied thereto.Fig. 6 is an enlarged perspective view of two of the resilient platesshowing the manner in which said plates are fastened together. Fig. 7 isa cross section of one of the plates. Fig. 8 is a perspective view, on agreatly reduced scale, of a wire hoop, the coils of which extend aroundthe wheel longitudinally of the tire. Fig. 9 is an enlarged sectionaldetail of the joint between adjacent plates of the tire.

Referring in detail more particularly to the forms of the tire shown inFigs. 1 and 2 of the drawings, 1 designates the spokes and 2 the fellyof the wheel. 3 designates a rim of well-known construction providedwith fastening rings 4, 5 and 6. The tire proper j consists of a seriesof resilient plates 7 formed Be it known that I, NELS H. HAssEL, a

of steel or like material, said plates being provided with curled endextensions 8 and 8 and side extensions 9 and 9 as more clearly shown inFig. 6. In Fig. 1, 1O designates the side plates nearest the center ofthe wheel, said plates being provided with outwardly curved portions 11adapted to fit into the concave inner sides of rings 5 and 6.

The curled extensions 8, 8 and 9, 9 all project toward the same face ofeach of the plates 7, in order that when said plates are united so thatthe curls project toward the interior of the tire, a smooth andcontinuous exterior surface is provided adapted to form the thread andouter side portions of the tire, as shown in Fig. 3, without anyexterior covering necessarily being used, or in the form of the tireshown in Fig. 1 the smooth exterior surface formed by said plates mayhave a covering placed thereover without danger of said covering beinginjured by the curls for fastening plates 7 together. The assembling ofthe various plates 7 in such a manner that the curls thereof all projecttoward the interior of the wall of the tire is made possible by formingthe curls, as best shown in Figs. 6 and 7, with a curl at one end curledaway from the body of the plate and a curl at the other end curledtoward the body of the plate, the side curls likewise being formed onecurling toward and one away from the body of the plate. This arrangementprovides for uniting the plates with the body portions thereof extendingin the same plane.

Along the inner side of the tire extends a metallic sheet composed ofside plates 12 and key plates 13, specially formed and interlocking withside plates 1.2 as best shown in Fig. 1.

A transverse partition composed of a series of cross plates 14 and 15serves to brace the side walls of the tire and to prevent undue lateralexpansion of the the under the weight of the vehicle. Said plates areunited by curled edge portions in a manner similar to the plates formingthe sides of the tire, said partition desirably extending entirelyaround the wheel.

Along the tread of the wheel is provided a series of thickened plates16.

18 designates a semi-solid filling of resilient material serving thedouble purpose of giving added resiliency to the tire and of keepingwater from entering between the joints of the plates forming the treadand adjacent portions thereof. One or more holes 19 may be providedthrough plates 14 or 15 to allow said filling when introduced in asemi-fluid form to pass from the inner to the outer chamber of the tire.

The tire may be prevented from collapsing by any suitable means whichoccupy the in terior thereof in such a manner as to hold the wallsdistended. For this purpose any suit able filling may be employed.

It is to be understood that fillings of the character mentioned may beintroduced when in a partly fluid form and afterward harden into anearly solid but highly resilient state.

In Fig. 3 the telly 2 is provided with a rim 4 having side portions 5.The plates used to form the tire as shown in Fig. 8 are similar ingeneral construction to those shown in Fig. 1 and are therefore notdescribed in detail but are designated by similar numerals with theaddition of an appropriate exponent. In this figure, 20 designatesresilient braces extending from the edges of the inner portion of thetire to points along the tread thereof. To give the tire requiredstrength, said braces may be continuous or may extend only partly aroundthe tire. The bracing plates may be held in place by means of curledends that curl into the plates at the sides of the tire as shown inFigs. 1 and 3.

In Fig. 5, rim 2" is provided with a concave periphery upon which thetire is sprung into position on the wheel as shown and is prevented fromlateral expansion by means of tie plates 21, having curls at each endinterlocking with similar curls of the side plates 7". 22 designates athickened tread plate.

Around the wheel in the forms of the the shown in Figs. 1, 2 and 5 mayextend three or more coils of heavy resilient wire 23, to strengthen thewheel and add to the resiliency thereof.

As shown in Fig. 7, the plates are tapered at the edges so that saidedges may be coiled to form interlocking fastening means as alreadystated. In assembling the plates 7, each pair of curls are slid togetherin an endwise manner, said curls not extending quite to the corner ofthe plates but an unobstructed space being left at the corners in ordernot to interfere with one curl being slid into engagement with theother.

As shown in Fig. 9, the curl 8 of one plate 7 curls into the curl 8 ofthe adjacent plate with a friction-tight fit between the inner ends 8and 8 of the curls. The plates 7 possess sufficient resiliencythroughout their curled portions and adjacent edge portions so that whenthe plates are somewhat straightened at the bends 8 and 8 by passingover an obstacle, said plates tend to spring back to the normal positionshown in Fig. 9.

A covering 24 of leather or like material may be provided for the tire,and said covering may have a thickened tread portion 24 andanti-slipping projections 24.

The curls of plates 7 are resilient and therefore take up the wear andco perate with thefilling to deaden noise by preventing rattling at thejoints between the plates. Said. plates form an armor for the wheel,said armor being prevented from collapsing and rendered resilient by thefilling 18 assisted by the loops of the spring hoop 23 (see Figs. 1, 2and 8) when said hoop is used.

Although I have shown what I deem the best manner of constructing a tiremade according to the principles of my invention, it is to be understoodthat various changes within the scope of the claims, such as may suggestthemselves to a skilled workman, may be made without departing from thespirit of the invention.

I claim:

1. A tire comprising a tubular frame composed of a multiplicity ofmetallic plates, said plates being provided with interlocking end andside extensions at their edges for fastening adjacent plates together,said extensions being formed projecting solely to ward the faces of theplates next the interior of the tire, and a resilient filling in saidframe to prevent the collapse thereof.

A tire comprising a wall formed of a plurality of approximatelyrectangular plates, said plates having curled extensions extending alongthe end and side edges thereof and projecting solely toward one face ofsaid plate, one of said curls being of less length than the edges of theplate from which it projects to provide an unobstructed space at thecorner of the plates permitting the curls of different plates to be slidinto engagement with each other, and a resilient filling in said tire.

3. A tire comprising a tubular wall composed of a multiplicity ofmetallic plates, said plates being provided with interlocking curledextensions at their edges for fastening adjacent plates together, saidcurled extensions projecting solely toward. the inner side of the tire,and braces within the tire, said braces having curled ends, curled intothe curls of a plurality of said extensions.

In testimony whereof I have hereunto signed my name in the presence oftwo subscribing witnesses at Los Angeles, in the county of Los Angelesand State ofCalifornia, this nineteenth day of October, 1907.
